Description
Technical field
The utility model is related to medical instruments field more particularly to a kind of uterine cavity stents.
Background technology
In gynecological surgery, after uterine neck is cut off due to cervical carcinoma, congenital cervical atresia, wound etc., easily send out
Raw cervical adhesion, leads to the menses of patient cannot discharge, generate abdominal pain, and the insertion stand tube at uterine neck is needed to strut uterine neck.
Due to no dedicated equipment, the method used at present is the insertion drainage tube at the uterine neck of patient, by drainage tube by uterine neck
It struts and avoids adhesion, meanwhile, menses can also be flowed out by drainage tube.But existing drainage tube is hose, in internal pressure of uterine cavity and gravity
Under the action of, drainage tube is easily fallen off, and cannot not only play therapeutic effect, can also bring secondary injury to patient.Also have
Medical worker adds retainer ring in drainage tube one end, but drawback is apparent, and one side retainer ring easily and Asherman's syndrom, causes to take ring
Difficulty increases the pain of patient, and another aspect retainer ring can be easily separated with drainage tube, and drainage is caused to fail.
Utility model content
The utility model overcomes uterine cavity drainage tube of the prior art and is inserted into the caducous shortcoming of uterine cavity content, provides
A kind of uterine cavity stent.
The utility model realize goal of the invention the technical solution adopted is that：A kind of uterine cavity stent, the uterine cavity stent packet
Include support portion and conduit, support portion is hollow oblate spheroid structure, even on the housing of support portion to be laid with through-hole, the shell of support portion
Body is the double-layer structure comprising interlayer, and being equipped in the interlayer of housing has elastically-deformable support frame, the space exhibition of support portion
Show that posture is corresponding with uterine cavity form, the housing of support portion is externally provided with medication coat, the lower end of support portion by arc section with
Conduit is connected to form one structure.
Further, the medication coat is equipped with the drug practised contraception and control endometriosis.
Further, the conduit is equipped with scale.
The beneficial effects of the utility model are：The support frame of the utility model improves the crushing resistance of stent entirety, profit
It is kept in form, it is not easily to fall off.The spring function of support frame is convenient for implantation and takes out.Support portion shape close to uterine cavity shape,
Compatibility is good, and uterine cavity polyp will not be stimulated to be formed.Meanwhile stent is inserted into uterine cavity, can also be had both treatment function, be passed through drug
Slow releasing function is practised contraception or treatment endometriosis.
The utility model will be further described with specific embodiment below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the A direction views of Fig. 1.
In attached drawing, 1-1 is conduit, 1-2 is support portion, 1-3 is medication coat, 1-4 is through-hole, 2 is support frame.
Specific embodiment
As shown in drawings, a kind of uterine cavity stent of the present embodiment, including support portion 1-2 and conduit 1-1.Support portion 1-2 is
Hollow oblate spheroid structure.In order to keep the unimpeded of uterine neck, to drain menses, on the housing of support portion 1-2 it is even be laid with it is logical
Hole 1-4.Through-hole 1-4 is arranged on the upper end and side of support portion 1-2, is flowed into and supported by through-hole 1-4 convenient for intrauterine menses
In portion 1-2.The housing of support portion 1-2 is the double-layer structure comprising interlayer, and being equipped in the interlayer of housing has elastically-deformable branch
Support bone frame 2.The housing of support portion 1-2 is wrapped in outside support frame 2, prevents support frame 2 from deviating from.Support frame 2 can be whole
Body structure can also use separate structure.The space representation posture of support portion 1-2 is corresponding with uterine cavity form, conducive to support
Portion 1-2 is placed in uterine cavity.The housing of support portion 1-2 is externally provided with medication coat 1-3.Drug directly or with polymer substrate is mixed
The surface of shell of support portion 1-2 is coated on after conjunction, uterine cavity stent is made to become a local drug delivery system.The present embodiment is preferred
Medication coat 1-3 be equipped with practise contraception and control endometriosis drug.The lower end of support portion 1-2 by arc section with
Conduit 1-1 is connected to form one structure.The hollow space of support portion 1-2 combines the channel to form menses outflow with conduit 1-1.For
Convenient for the length that observation conduit is inserted into, the present embodiment preferred conduit 1-1 is equipped with scale.
In actual use, uterine cavity stent is inserted into intrauterine along the vagina of patient.In insertion process, built in support portion 1-2
Support frame 2 deform upon under external force, volume contraction, convenient for stent be inserted into.After portion 1-2 to be supported enters uterine cavity,
Support frame 2 restores deformation, and for the shape of support portion 1-2 close to uterine cavity shape, compatibility is good, and uterine cavity polyp will not be stimulated to be formed.
Support frame 2 improves the crushing resistance of stent entirety, uterine cavity stent can Preserving time it is internal, menses are drawn by uterine cavity stent
Stream, maintains the unimpeded of uterine neck, meanwhile, pass through the medicament slow release effect contraception of medication coat 1-3 or treatment mullerianosis
Disease.
